Dear @m-arita, a good friend of MassBank reported some issues with RIKEN derived mass spectra. Could you curate the records, please?

Some of the exact masses provided by Riken are incorrect. An example: searching for compounds with an exact mass of 294.398 daltons (impossible mass defect) +/- 0.005 gives four hits (attached). Looks like atomic weights were used instead of exact masses.

Best wishes,
Tobias

This problem is maybe also related to #125. We may find a good solution for manual curation? @meier-rene @sneumann
